IMPROVEMENT IN GORN PLOUGHS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOHN'HINDMARSH, of Henry, in the county of Marshall,and State of Illinois, have invented a new and improved Corn Plough; andI do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, reference being had to the accompanying drawings,forming part of this specification, in which Figure 1 is a plan or topview of my invention.

Figure 2, a side sectional view of the same, taken in thedine a: z, fig.1.

Similar letters of reference indicate like parts.

This invention relates to a new and improved plough for cultivating cornand other crops,grain in hills or drills; and it consists in a novelmanner of applying the ploughs to the machine whereby the former may beraised and lowered, and also moved laterally by the manipulation of asingle lever, and the ploughs thereby placed under the complete controlof the dniver, and made to conform to the sinuosities of the rows ofplants; the invention also admitting of the ploughs being set oradjusting to plough at a greater or less depth, as may bedesired.

A represents a rectangular frame, which is mounted at its rear part onthe wheels 13 B, the axles a of which are bent or are of curved form,and attached to the under side of A. C is the draught-pole attached tothe frame A, and b b are two oblique bars, which project from the rearof A, and have the drivers seat D attached to their rear ends. E is adouble tree attached to the rear part of the draught-pole C, and havingwhifiie-trees, F F, attached to its endsby rods, 0 c; G G are ploughbeams, the front ends of which are attached by joints, d d, to the lowerends of pendants, H H, at the front part of the frame A, one at eachside, saidjoints, d d, admitting of the rear parts of the beams G beingraised and lowered. The rear end of each beam, G, has a standard,"

I, attached to it, and to the lower ends of these standards ploughs Jare attached of the usual cultivator form. To the inner side of eachbeam, G, a bracket, K, is attached, said brackets inclining slightlyinward from their lower to their upper ends, and having ploughstandards, L L, attached to them by hinges or joints, e e. The ploughsL, which are attached to L L, may be of the same shape, as thoseattached to thestandards L. These standards, L L, extend upwards abovethe level .of the drivers seat D, and they are connected at their upperends by a cross-bar, M, the ends of which are pivoted to L L. N is alever, the front end of which is connected by a joint, f, to the rearend of the draught-pole C, said lever passing through an opening, g, atthe centre of M, and extending back within reach of the driver on seat1). Each plough beam, G, has a rod, O, attached to it,

and these rods pass up through guides, 71, h, at the. inner sides ofbrace-bars, ii, in the framing, and are con nccted at their upper endsby a. cross-bar, P, through the centre of which a set-screw, Q, passes.By adjusting this screw, Q, the depth of the penetration of the ploughsmay be regulated as desired, and it will be seen that the driver, bymanipulating the lever N, may ,raise andlower all the ploughs, and movethe inner ones laterally to conform to the sinuositics of the rows ofplants. The lever N has a pendent standard, 0*,attached, which, when theploughs are raised, rests on therear part of the draught-pole andsustains the ploughs in an elevated position. The standards L L arebraced by rods, y, from the front parts of the beams G G, said rodsbeing conncctcd byjoints k to G and L.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent-- I 1. The lever N, in combination with the standard0*, for sustaining the ploughs in an elevated positionpwhen required. i

2. The rods 0 O, plough beams G G, cross-bar P, and screw Q, combinedand operating as described.

3. The combination of the plough beams G G, standards L L, lever N, andbrace-rods 7', all arranged and applied to a mounted frame, A, tooperate in the manner substantially as and. for the purpose specified.
